serverless-log-forwarding-kinesis

Serverless plugin for forwarding CloudWatch logs to a Kinesis Stream

Getting Started

Prerequisites

This plugin only works for Serverless deployments to AWS

Make sure you have the following installed before starting:

• nodejs
• npm
• serverless

You will need a Kinesis Stream ARN, and the ARN to a role with a policy like:

CloudWatchLogsRole:
  Type: AWS::IAM::Role
  Properties:
    AssumeRolePolicyDocument:
      Version: "2012-10-17"
      Statement:
        - Effect: Allow
          Principal:
            Service:
              - logs.amazonaws.com
          Action:
            - sts:AssumeRole
    Policies:
      - PolicyName: root
        PolicyDocument:
          Version: "2012-10-17"
          Statement:
            - Effect: Allow
              Action:
                - kinesis:PutRecords
                - kinesis:PutRecord
              Resource:
                Fn::GetAtt:
                  - KinesisStream
                  - Arn
    RoleName: kinesis-forwarder-cloudwatchrole

Note the above is just an example cloudformation resource, and you will need to create one appropriate for your use case.

Installing

To install the plugin, run:

npm install serverless-log-forwarding-kinesis

Then make the following edits to your serverless.yaml file:

plugins:
  - serverless-log-forwarding-kinesis

custom:
  logForwardingKinesis:
    destinationARN: '[ARN of Kinesis stream to forward logs to]'
    roleARN: '[ARN of the role to use when forwading logs]'
    # optional:
    filterPattern: '[filter pattern for logs that are sent to Kinesis]'
    normalizedFilterID: true # whether to use normalized function name as filter ID
    stages:
      - '[name of the stage to apply log forwarding]'
      - '[another stage name to filter]'

functions:
  myFunction:
    handler: src/someHandler
    # optional properties for per-function configuration:
    logForwarding:
      # set enabled to false to disable log forwarding for a single given function
      enabled: false

Running Tests

To run the test:

npm test

All tests should pass.

If there is an error update the node_module inside the serverless-log-forwarding-kinesis folder:

npm install

Deploying

The plugin will be packaged with the lambda when deployed as normal using Serverless:

serverless deploy
